Right Triangle Sun Shade Sail 13ft x 20ft x 23.9ft - High UV

In this review of the Right Triangle Sun Shade Sail, the bottom line is simple: it is best for homeowners and small businesses who need a durable, heavy-duty triangle canopy that reliably blocks sun and lowers temperature. The reviewer found the sail's standout advantage to be its combination of a thick 200 GSM HDPE weave with a stated 95% UV blockage, which produces noticeably cooler shaded areas and long-term stability under sun and wind. Installation is flexible enough for DIYers who can measure from D-ring to D-ring and plan anchor spacing in advance.

Key Features

• 95% UV blockage: The fabric blocks up to 95% of harmful rays, providing safer shade during peak sun hours.
• 200 GSM HDPE material: A heavy commercial-grade weave that resists fraying and stands up to repeated sun exposure.
• Temperature reduction: The sail reduces ambient temperatures by as much as 15 degrees compared with unshaded areas for a cooler patio or yard.
• Stainless steel D-rings: Reinforced corners with stainless fittings and double-layer stitching improve longevity under tension.
• Custom size fit: Made to measure from D-ring to D-ring so the shade matches your exact space when ordered to make.
• Water and air permeable: The breathable weave sheds some water and allows airflow to avoid heat trapping beneath the canopy.

Who It's For

The sail is ideal for homeowners, cafes, or community spaces that need a robust triangle shade that holds up to wind and prolonged sun exposure; users who want a tailored fit will appreciate the custom sizing from D-ring to D-ring. It is also a good choice for DIY installers who can plan anchor points on trees, posts, or walls and follow the recommended corner gaps for best tension.

Those who should look elsewhere include buyers seeking a fully waterproof awning or a lightweight seasonal product; this is a breathable HDPE canopy made to reduce sun and heat rather than to act as a rainproof tarp. Also, shoppers who prefer off-the-shelf small sizes may find custom ordering unnecessary.

Pros & Cons

Pros

• Durable commercial 200 GSM fabric that customers report holds up well even in strong sun and wind.
• Effective shade and temperature reduction, making outdoor areas noticeably cooler.
• Reinforced edges and stainless steel D-rings with double stitching for long-term use.
• Custom sizing option gives a precise fit for irregular or specific layouts.

Cons

• The breathable HDPE fabric is not fully waterproof, so it does not replace a rainproof canopy in heavy downpours.
• Some buyers report the final measured size can feel smaller than expected if measurement from D-ring to D-ring is not exact.

Frequently Asked Questions

Is this sail waterproof?
The HDPE weave is water permeable and not fully waterproof; it sheds some water but is designed primarily for sun protection and airflow.

How should I measure for a custom fit?
Measure from D-ring to D-ring at each corner and allow the recommended gap of about 0.5 ft from anchors, reducing by 1 to 1.5 ft per side if needed for tension planning.

Will it reduce temperature under the shade?
Yes; customers and product guidance indicate it can reduce ambient temperature by up to about 15 degrees compared with unshaded areas.
